Proving it was no fluke, he followed that up with a 4.37 in his second rotation. Although it wasn't the sub-4.3 time for which he had hoped, Peterson was impressive blazing down the fast track of Lucas Oil Stadium.

Peterson probably maintained his distance from Nebraska's Prince Amukamara — who earlier on Tuesday ran a 4.37 — as the top cornerback prospect. On air, NFL Network analysts Deion Sanders and Mike Mayock said Amukamara looked a bit "tight in his hips" during the pass coverage drills.

Looking well beyond his speed, Peterson proved what most scouts have already learned — he is a terrific all-around corner with great size at 6-0 1/4, 219.
